Data Modeler - London Markets

We're looking for a dedicated Data Modeler to join a leading organisation in the London markets. This is a hands-on contract role (not an Architect, not a Developer-who-dabbles, not a Manager-in-hiding). You'll be Laser-focused on designing and delivering enterprise-grade data models across warehouses, lakes, and vaults.

The Role

You'll be responsible for:

• Designing and developing conceptual, logical, and physical data models.

• Implementing models across RDBMS, ODS, data marts, and data lakes (SQL/NoSQL).

• Translating business needs into robust, long-term data models.

• Applying Data Vault 2.0 techniques in real-world implementations.

• Supporting metadata management, governance, and best practices with tools like Erwin or ER/Studio.

What We're Looking For (Must-Haves)

• 5+ years hands-on experience as a Data Modeler (your CV should scream "Data Modeler," not hide it in bullet 17).

• 2+ years hands-on Data Vault modelling.

• Strong background in data warehouses, data lakes, and enterprise big data platforms in multi-data-centre contexts.

• Proficiency with metadata management and data modelling tools (Erwin, ER/Studio, or similar).

Nice-to-Haves

• ETL/Data Transformation experience - ideally Qlik Compose or AWS Glue (alternatives like DataStage, SSIS acceptable).

• Cloud exposure (AWS preferred).

• Familiarity with modern dev methodologies (Agile/Scrum, TDD).

• Knowledge of testing tools, Scripting, and data cleansing techniques.
